In a “real” terminal (I mean the ones you get to by Ctrl + Alt + F2 through F9 except F7), can you scroll up beyond the top edge of the monitor the way you could beyond the top edge of the window in a terminal emulator?
If that is not possible, can you tell the real terminal to save its output to a file (in addition to showing me real time) so that I can later look at it? Thanks.
Just to add some further clarification to the replies above, it used to be possible to scroll up in a tty by using Shift+PgUp and/or Shift+↑, but considering that the framebuffer for the Linux console is coded in the kernel, this code for allowing scroll-back in a tty was dropped from the kernel at some point.
It may however still work if you’re running an older LTS kernel — I’m not sure anymore when exactly the code was dropped, but I’m guessing that it’ll still work in the currently still supported 4.x LTS kernels.
